Y To all whom t may concern:

` Be it known that' I, vRAYMOND PEN- EIELD, a citizen of the United States lof America, residing at New York city, in the` A, tus yfor sprinkling` sand over successive layers or courses of brick as the latter are placed in setting formation preparatory to being burned.

In making various kinds of brick, it is necessary, in order to prevent the bricks from sticking or adhering together when burned in the kilnfto sprinkle sand over the successive layers as rvthey are piled up in y setting formation. This has heretofore been ldone by hand. Such hand sanding of the bricks necessitates the `employment of eX-` tralabor, or takes upl thetime of the-men setting the bricks, and, moreover, thesand is usually distrbutedunevenly and parts of the bricks are leftunsandedwith the result that when they arev burned someA of thefbricks stick together and are ruined or damaged. i

:'Thefobject of the present inventionis to provide a brick sanding machine or apparatus which will dispense'with hand labor y in sanding the bricks, and which will op-` crate vto distribute the sand in an even, uniform layer overy the successive courses of*l brick as they are piledy up, and'whichrwill do this without care or attention,l beyond the ymere throwing cfa lever or other def vice for starting the `mechanism in operation after each course of brick is laid. n ,A full understandingof the invention can best be given by a detailed description of a preferred form. of brick sanding machinev embodying the various features of the invention, yand-such av description will now bek n given in connection with theaccompanying drawings, in which Figures 1 and 11av showV the machine in sideelevation withv parts broken away and parts in section. Fig( 2j is a plan viewk of the machine with v portions 'of the Vlongituiilimany eXteld-Ilg Darts of the.construction" broken away andwiththe end portions of the construction brought together. Fig. .3 is Van end View ofthe machine looking in the direction of ythe yarrow 3 on Fig. 2 with parts ojnfiittedV jfor the sake of clearness. Fig. tis a detail hereinafter explained. n

Referring to the drawings, t-he various oper- I ative and other parts of the machine as shown are carried by ahorizontal frame formed of side bars 10 and 11 and cross connecting I bars 12. This framemay befsupportedin any suitable manner. As shown it is sup-"-V ported fromabove by hangers 13. The ma-f 7 -chine shownisintended especially to be used f for sanding bricks as they are hacked on the drycars after coming from the cuttersor repressers, and when so used the frame will be supportedy over the car tracks and at aI '7 sufficient heightr so as not tointerfere with setting of the bricks on the car.` Y f Mounted tomove longitudinally back and *forth/on the side bars 1Q andll, is a sand distributing device 14 comprising a sand s holder or hopper 15 and'means for dropping the sand from the hopper as it travels back and forth. rlfhe hopper .is formed' by inclined sides 16 extending between and cary ried by end 'plates 17 'Ihe plates 17 ezi-` 8 tend ,below the sides of the hopper and carry bearings for two shafts 18, onthe ends of which are mountedrunning wheelsor rollers 19 which run on rails 2Q secured tothe tops `of the side bars 10 and 11 to`form a tracks for the'distributing device. n 4rails 2O isformed with a longitudinally eX- ltending rack 21 which, as shown,is`arranged Each if of the centrallyk of the rail, the treadof the runy' Vning wheels v19 beingcentrallyrecessed or 9 grooved to lreceive therack and allow the wheels to rest onthe track on either side of l' the rack. kThe lower edgeskof the sides 16 of the hopperv are separated and the open bot- 1 tom thus formed lis closed by a feedingroll 1 22 which is carried by shaft23 mounted lin bearings on the end plates 17.l The shaft .23 carries ybeyond'the end plates 17 pinions 24 whichgear with the racks21, so that 'as the hopperfismoved in either direction on 1 the rails 20 the feeding roll`22willrberotated .to carry sand from the hopper vand OOy dropv` iton to the bricks over which the hopy l per is being moved. The ysurface off-the feeding roller .will lpreferablyi be grooved v1 yor-ffluted, as shown, orvotherwise formed Y with `pockets for positively ,feedingsandn 1 from the hopper. In order to prevent the escape of sand from the hopper when the roller is stationary, shields or aprons 25 may be provided, extending outwardly and downwardly from the lower edges of the sides of the hopper over the surface of the feeding roller, and made preferably of suitable flexible material such as heavy rubber and canvas fabric.

The sand distributer is caused to travel back and forth by means of sprocket chains 30 which are connected therewith, and which run on driving sprocket wheels 31 fast on a shaft 32 mounted in bearings 33 on side bars 10 and 11 at one end of the frame, and on sprocket wheels 34 carried by a shaft 35 mounted in bearings 36 on the side bars 10 and 11 near the other end of the frame. The shaft 32` is driven from either one of two driving pulleys 40 and 41 which are mounted to run freely on the shaft, and each of which is provided with a clutch mechanism, not shown, but which may be of any suitable construction, and which through the action of clutch arms 42 and 43, respectively, may be operated to cause the shaft to rotate with its driving pulley. The clutch arms 42 and 43 are operated to clutch the respective driving pulleys to the shaft by means of a sliding cone sleeve 44 mounted on the shaft 32 between the driving pulleys and provided with oppositely inclined cones for engaging the ends of the clutch arms, so that when the cone sleeve is moved to the left in Fig. 3 the clutch arm 43 will be thrown to cause the shaft 32 to be rotated by the pulley 41, and when the cone sleeve is moved in the opposite direction the clutch arm 42 will be moved to cause the shaft to be driven by the pulley 40. rlfhe pulleys 40 and 41 will be driven in opposite directions by belts from a counter-shaft or in any other suitable manner.

The cone sleeve normally stands in the position shown in Figs. 2 and 3 in which position both driving pulleys are disconnected from the shaft 32, and the sleeve is moved for connecting one or the other of the driving pulleys with the shaft through the operation of a branched shifting lever 50 which carries pins 51 which extend into a groove formed by collars 52 on the sleeve. The lever 50 is pivotally mounted below the cone sleeve on a bracket 53 extending from the cross bar 12, and the upper end of the lever is connected b v link 54 with an arm 55 extending upwardly from a rock shaft 56, which shaft also carries a downwardly extending hand lever 57, so that by throwing the hand lever 57 to the right in Fig. 3 the shaft 32 may be connected with the driving pulley 41, and by throwing the hand lever to the left, the shaft 32 may be connected to the driving pulley 40. The rock shaft 56 is mounted in bearings on the side bar 11 and is preferably extended to carry a second hand lever 57 at a convenient point near the far end of the machine.

To provide for automatically stopping the movement of the sand distributer as it reaches the end of its run in either direction, a rock shaft 60 is provided at the opposite side of the machine from the shaft 56 and mounted, as shown, in bearings formed in lugs extending upward from the bearings of the shafts 32 and 35, which shaft 60 is connected with the shifting lever 50 by means of an upwardly extending arm 61 and a link 62. The shaft 60 also carries two arms 63 and 64 which are adapted to be engaged by a cam plate 65 carried by the sand distributer, so that as the distributer reaches the end of its run in either direction, the shaft 60 will be rocked to cause the shifting lever 50 and the cone sleeve 44 to be returned to position to disconnect the shaft 32 from whichever driving pulley it was being driven by. Fig. 4 shows in full lines the normal position of the shaft- 60 and arms 63 and 64 to which they are returned by the cam plate 65, and shows also by dotted lines the position taken by the shaft and arms when the driving pulleys are connected with the shaft 32. The posit-ion of the arms 63 and 64 longitudinally of the shaft 60 will determine the distance to which the distributer will run, and these arms are preferably adjustable on the shaft 60 so that the movement of the distributer may be regulated as desired. As shown, these arms are carried `by sleeves mounted to slide on the shaft 60 and secured in position by means of set screws.

rThe sand holder or hopper of the traveling distributer may be made of any convenient or desired size and may be supplied with sand in any suitable manner. Preferably, however, means are provided for automatically supplying sand to the traveling hopper. For this purpose there is provided in the construction shown a supply hopper which is mounted above the position of rest of the traveling hopper at one end of the machine, and is formed with a plurality of nozzles, each of which is provided with a horizontally swinging gate 71 for closing the nozzle and preventing the escape of sand therethrough. These nozzle gates 71 are arranged to be automatically opened as the traveling distributer reaches its position of rest beneath the supply hopper, and to be automatically closed as the distributer moves forward from beneath the supply hopper. For this purpose, each of the gates 71 is provided with two downwardly projecting lugs 72 and 73, respectively, which may be provided with anti-friction rollers as shown, and which lugs are engaged by upwardly projecting plates 74 on the right hand side of the hopper 15 in Fig. 1a.

The

7 3 y'will stand in the path of movement of such plate 74. As the 4distributer approaches the end of itsmovement to lthe right in Figs. 1 and la and 2, the plates 7 4 will engage the lugs 7 2'and the gates will be y opened byr thecontinued movement of the,y

' distributer. When thedistributer comes to rest in 4the posit-ion shown in Fig. 1a, the x lugs 7 3 will have bee-nmoved in behind the plates 74 and will stand inthe path 'of the plates, so that when the distributer vstarts on its movement to the left from the position shown in Fig.'1a,the lugs v7 3 will be engaged by theplates 74 to causeL the hopper` gateslto be closed, and by the swinging movement of the gates to their closed position, the lugs 73 will beswung out of the path of movement` of the yplates 74, and the lugsf72 willbe moved into the path of the plates in position forthe opening ofthe gates atkthe end of the next movement vof the distributer. V'The supply hopper 70 may be fed by a chute or chutes 8O from a conveyer or bin or by other suitable means. e

The operation is as follows: The parts of the'` mechanism described, with the exception of the driving pulleysl and 41, will normally'be at rest. -With the traveling `distributer in the position shown by fulllin'es o in the drawings, when it is desired to start 40 themachine to cause sand to be distributed on a layer of brick,"o-ne of the hand levers 57 will be thrown to the right in Fig. 3, to

connect the driving pulley 41 with the shaft4 32 and to rock the shaft 60 to throwv the arms `4,5 63 and 64 outward `to the position@ shown by dotted lines in Fig. 4; Thefshaft 32 will then be driven by the pulley 41 in thedirection to cause the distributer tomove tothe right from the position shown in full lines in Figs. 1a and 2. As the distributerstarts on such movement', the gates of the supply hopper 70 will be'closed, andV during all of such movement of the ydistrilout-er the feedf y ing roller 2l by reason of the engagement of the pinions 24 with therac'ks 21 will be y turned to carry sand from the hopper andy ydrop it on to the layerof `bricks over which Vthe hopper is traveling.V Just before the distributer reaches the end of its run, thev s cam plate 65 willcomeqfinto engagement with the arm `64 on the rock shaft k60 and will throw said armback to its'vertical`V position, thereby rocking the shaft 60and causing the shiftingv lever 50 land the cone lsleeve 44 to e fbe'returned to the central positionshown in ist.

yof within'the claim. It is to be, understood the drawings to' disconnect the pulley Y41 from the shaft 32. 4The ,movementl ofthe distributer will thereby be stopped and Ait will come to rest in the position indicated by dotted lines in Fig. 1, and as ythe feedingm roll 21 rotates` only during the' movement of thedistributer the feeding of the sand n from the' holder will also be stopped. NVhen another layer of brickis ready kto be sanded, the sand-holder will be startedon its moven 75 ment in the opposite direction by throwing one of the levers 57 to the left in Fig. 3 to connect the drivingpulley 40 with the shaft 32 and to rock the shaft 60to throwthe arms 63 and 64 inward to the position?) 30 shown by dotted lines in Fig. 4. The distributer will then move t-o the right from 'j `the position shownby dotted lines in Fig.y

1 andthe feeding roll will be turned as before, but in the Lopposite direction, tocause 35 the sand to be dropped fromthe distributer. The movement of the distributer andthe feeding'of the sandvwill continue until the distributer is stopped in the position shown by full lines in'Fig. k1a through the action of 9eV the cam plate 65 Onthearm 63 disconnect-A ing the pulley 40 from the shaft 32. As the distributer runs beneaththe supply hopper 70,the gates 71 willbe opened and sand will flow from the hopper 70 to replenish 95 thesupply inthe traveling hopper. The flow of sand from the hopper will cease when the sand in the traveling hopper yreaches the nozzles 4of the rhopper, 70 as shown in Fig. 1a, and the gates 71 will be 100 closed when the distributer starts on itsneXt movement as above explained.

, It willbe understood that the invention is not to :be limited to the exact construction and arrangement of parts as shown in the drawings and to which the foregoingde-r scription hasy been mainly confined, but that it includes changes and modications therefurther, that fthe term sand and sanding used in the claimfisnot to be con strued asa limitation, and that the construcf tionsY claimed may be employed y.for the distribution of othermaterials for which they may be found adapted. p
